6 1 Product Description The TPMC461 is a standard single-width 32 bit PMC module and offers 8 channels of high performance serial interface. Three different standard modules are available: The TPMC461-10R provides 8 RS232 interfaces. The TPMC461-11R provides 8 RS422 interfaces. The TPMC461-12R provides 4 RS232 and 4 RS422 interfaces. Other configurations are available as factory build option on a per channel base. All modules offer front panel I/O with a HD50 SCSI-2 type connector and P14 I/O. Each RS232 channel supports RxD, TxD, RTS, CTS and GND. Each RS422 channel supports RxD+/-, TxD+/- and GND. Two channels of the TPMC461-10R/-12R offer full modem support (TxD, RxD, CTS, RTS, DSR, DTR, CD, RI and GND) for RS232. Two channels of the TPMC461-11R support RxD+/-, TxD+/-, RTS+/-, CTS+/- and GND for RS422. Each channel has 64 byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to kbps for RS232 channels and Mbps for RS422 channels. The UART offers readable FIFO levels. All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special Global Interrupt Source Register. All serial channels use ESD protected transceivers. ESD protection is up to ±15KV. The TPMC461 can operate with 3.3V and 5.0V PCI I/O signaling voltage.

18 6 Programming Hints 6.1 UART Baud Rate Programming Each of the 8 UART channels of the TPMC461 provides a programmable Baud Rate Generator. The clock of the XR17D158 UART can be divided by any divisor from 1 to The divisor can be programmed by the UART channel DLM (Divisor MSB) and DLL (Divisor LSB) registers. After a reset bit 7 of the UART channels MCR register defaults to 0 and the divisor value is 0xFFFF. The basic formula of baud rate programming is: Baud Rate = MHz 16 Divisor ( 1+ 3 MCR[ 7] ) Examples for standard baud rates are given in following chart: Baud Rate MCR[7] = 0 Baud Rate MCR[7] = 1 Divisor DLM Value DLL Value x1B00 0x1B 0x x1200 0x12 0x x0900 0x09 0x x0480 0x04 0x x0240 0x02 0x x0120 0x01 0x k x0090 0x00 0x k x0048 0x00 0x k 14.4k 0x0030 0x00 0x k 28.8k 0x0018 0x00 0x k 57.6k 0x000C 0x00 0x0C 460.8k 115.2k 0x0006 0x00 0x k 230.4k 0x0003 0x00 0x M 345.6k 0x0002 0x00 0x M 691.2k 0x0001 0x00 0x01 Table 6-1 : UART Baud Rate Programming To calculate a divisor value for a given baud rate, use following formula: Divisor = MHz 16 Baud Rate ( 1+ 3 MCR[ 7] ) The sampling rate for a UART channel can be set to 8x (normal operation is 16x) in the 8XMODE register. Transmit and receive data rates will double by selecting 8x sample rate. The maximum achievable baud rate is Mbps (Divisor = 0x0001 & 8x sampling rate). TPMC461 User Manual Issue Page 18 of 26

19 These steps should be used to modify the DLM, DLL registers of an UART channel: 1. Write 0x80 to the LCR register of the UART channel (enable access to the DLM, DLL registers). 2. Program the DLM, DLL registers of the UART channel. 3. Write normal operation byte value to the LCR register of the UART channel. These steps should be used to modify MCR register bit 7 of an UART channel (set baud rate generator prescaler): 1. Set UART channel EFR register bit 4 to '1' (enable modification of MCR register bits 5-7). 2. Modify UART channel MCR register bit Set UART channel EFR register bit 4 to '0' (latch modified MCR register setting). Note that the maximum baud rate for RS232 channel is kps. Thus the minimum divisor value for RS232 channels is 0x0003 with MCR[7] = RS422 Flow Control Only UART channels 0 & 1 allow using RS422 with RTS/CTS flow control. On channels 2 7 the CTS# input is hardwired to 1, so that no RTS/CTS flow control is possible. TPMC461 User Manual Issue Page 19 of 26

20 7 Pin Assignment I/O Connector Connect channel I/O either to front I/O or P14 back I/O at a time. Do not connect an I/O channel to both front I/O connector and P14 back I/O connector at the same time. RS422 channels provide on board 120Ω termination resistors. Do not apply additional external termination resistors here. Please note that on the TPMC461 the P14 back I/O connector is always populated and connected to on board logic. Do not use these modules on carrier boards where P14/J14 is reserved for other system signals but PMC I/O. In this case ask support for special board options with front I/O only.
